Āścarya-kathana: Brāhmaṇa–Nāga Dialogue on Sūrya (Vivasvat) and the ‘Second Sun’ Phenomenon
इक्ष्वाकुणा च कथितो व्याप्य लोकानवस्थित: । गमिष्यति क्षयान्ते च पुनर्नारायणं नूप
ikṣvākuṇā ca kathito vyāpya lokān avasthitaḥ | gamiṣyati kṣayānte ca punar nārāyaṇaṃ nūpa ||
毗湿摩波耶那说道:“伊克什瓦库也曾称述于他;他遍满诸世界而安住不动。待劫坏之终,他将再度归于那罗延那,噢,大王。”
वैशम्पायन उवाच
The verse frames worldly manifestation as temporary: a being (or principle) may pervade and sustain the worlds, yet at cosmic dissolution it returns to Nārāyaṇa. Ethically, it points to the supremacy of the divine source and the impermanence of all created states.
Vaiśampāyana continues a doctrinal narration, citing Ikṣvāku’s account as authority. He states that the described entity abides while pervading the worlds, and at the end of cosmic destruction it goes back again to Nārāyaṇa, addressing the kingly listener.
